For the outdoorsy, off-roading type, the 2018 Jeep Wrangler may be the nicest of the bunch. The iconic rugged-looking Jeep has been trimmed down with the use of aluminum in its structure for better fuel economy, a feature it's never been associated with. This theme continues under the hood with a new 2.0-litre turbo four with efficient eTorque technology. It will accompanied by the 3.6-litre Pentastar V6 with engine stop/start and a diesel-powered 3.0-litre V6 in 2019. An eight-speed automatic transmission or a new six-speed manual will be offered.
